easy access by the power plug.

Do not connect the earth (ground) to the following objects.

Water pipes

(Complete grounding is not possible as hard plastic pipes are widely

used.)

Gas pipes

(Can result in an explosion or ﬁre)

Lightning rods and telephone dedicated grounding wire

(Dangerous during lightning)

Do not touch the power plug or power outlet with wet hands.

Failure to do so can result in electric shock.

Use a single power outlet (do not share a power outlet with

other plugs).

Use an unshared power outlet with an attached ground terminal.

Using the same power outlet together with the power plug of other

devices can result in abnormal heat generation and possible ﬁre.

Firmly insert the power plug into the power outlet.

Be sure to fully insert the power plug into the power outlet until

reaching the base of the plug.

Failure to fully insert the plug or similar fault can result in a short circuit

or heat generation that causes a ﬁre.

Patient weight limit[440 lbs (200 kg)].

The seat may rise slowly if a person weighs close to the chair lift

capacity limit.

Shockless Mechanism

This product is equipped with a shockless mechanism, that allows

smooth starting/stopping chair movement.

This mechanism reduces chair vibrations, enabling smooth chair

operation.

To utilize this mechanism, pay attention to the following precaution;

Chair Preheating Function

Due to the product's hydraulic system and shockless mechanism, the

chair stopping position may slightly vary depending on the oil

temperature and patient weight.

The oil temperature will drop especially during winter season in the

mornings,creating a scatter in the chair stopping position.

When the oil temperature signiﬁcantly drops, the chair preheating

function will operate for 3 minutes immediately after the product's

main switch is turned on.

The warning sound will beep during this operation.

To cancel the chair preheating function, press any manual chair

movement switch or preset switch.
